Hi all

pretty please.
Sorry if this is the wrong thread, but I couldn't find one that is relevant to windows pc/laptops or cool reader for windows only.
I have a working knowledge of using a pc daily, and can figure out some basic issues, but not this time. I have no knowledge of coding.
My PC is a Dell Inspiron windows 7 64 bit laptop and I've been using cool reader (cr3-qt-win32-3.0.56-42 which I seem to have had since Dec 2014) as my epub viewer and my epub files are associated with cr3 so I just click the file I want to read and bam, it opens.
A few days ago it just stopped working. No error messages, no pop ups, no warning, nothing. It just doesn't open any files.

This is what's happened so far...
- I tried restarting my laptop a few times. Nothing.
- I went to Set Associations and there's no cr3 available?
- I went into the .exe file to open it just in case I had done something to shut it down unknowingly, and again, nothing happens.
- I went to the control panel to uninstall the programme, so I could DL it again, and there's no cr3 there to uninstall?
- I tried to "open as Administrator" and still, nothing happens (past the do you want to let this programme run...message).
- I couldn't find a dedicated cool reader website but I DL it again (cr3-win32-qt-opengl-3.3.61.zip the most up to date version I came across as I couldn't find the one I had) from a third party website and ran it through my virus scanner and the programme opened but I couldn't figure out how to add any files to view.
- I went to Set Associations again, cr3 is there now so I chose it as the default programme. And still nothing happens when I try to open a file.
Now I may well be missing something really obvious here. Or I may have inadvertently done something to it. And yes there are alternatives available (incl the calibre viewer) but you know when you like something, get used to it, and it works why change it? Especially when I just need it for basic viewing without any bells and whistles.
Does anyone have any idea what's going on? It's annoying the hell out of me and whatever the outcome, I just need to know.
Or has cool reader for windows become obsolete in the last few days? It seems odd to me that there is no website for it, but it seems to be all over many third party sites and there is loads of info available on the Android versions.
TIA for any help or advice.
